ARM aarch64 Support

[blaggacao]

Quite a few people might want to get up to speed with deploying their RPi (eg. Home automation, etc).

I'm going to think of a way on how to integrate it into flk so that the UX of getting started with raspberry (and other board) builds is cool.

I'm realizing that for RPi builds, it would make much more sense if the sd base configuration would actually be a "hidden" (from flk) module and instead each host would gain a flk sd <host> command. The same thing might actually be true for iso as well...

In other words, people would be encouraged to do flk iso <host> so to base off their ISO on a specific host config.

This could potentially be out of scope for this project, since we are primarily concerned with providing a template for NixOS personal use. shortsighted, it's in scope.

Alright, closing ... 👍

Maybe the flk iso <host> would be a good abstraction though (and be very sd flashing compatible)?

I'm trying to play the patient game and get this merged, so we can have (in theory) a SD image build.

Of course that would not do anything about package compatibility and such, but would be a first step to play around and see where we need amend things...

indeed, I think the missing piece are cross builds, as far as I can tell. I'm slowly getting to the point where I need crossbuilds to work, so I'll be probably following through on this. If you have any pointers or ideas, please let me know.

I want to be able to do flk sd NixOS so that NixOS will be crossbuild (in aarch64) for flashing on a sd card.
